Fuel is one of the research areas of major focus in recent days. This review paper is based on the principle that it may be possible to grow our way out of an energy crisis with renewable, recyclable plant - based fuels. In turbine aircraft , combust ion process acts on fan blades that either turn s a propeller or cr eate thrust by accelerating gas. The fuel used is jet fuel (jet - A, jet - 1A, jet - B). Biofuels have to replicate the characteristics of jet fuels in order to place a claim as future aviation fu el. The biggest challenge is to find out a renewable fuel which fits the bill. One such biofuel in the race is the 3 rd generation ‘algae’. There are few technical and legal issues in using algae for production of biofuel and they are: Technical issues: Die sel fuel stability (extremely high flash point and low volatility), Fuel freezing point temperature, Lack of lubricity, Low energy density. Legal issues: Renewable fuel standard, Clean air act, Toxic substance control act, Clean water act, Plant protection act, National environmental policy act, Endangered species act. The biofuels have to overcome these issues and be accepted by respective regulatory bodies. Use of biofuel s can reduce CO2 emission by up to 80% over their full cycle. Since algae consume CO2 while growing, it provides mitigation benefits on CO2. On stud ying algae growth , it has been found that the properties of algae vary depending on the fertilizers used to feed them. Using the turbine code in MATLAB , the calorific value of halophytic algae is analy z ed and compared with jet fuel and the graph (thermal and propeller efficiency versus compression ratio) is plotted to study their performance. This paper is about 1 st phase of the research. From the results obtained it is observed that the halophy tic algae have better performance compared to conventional jet fuel.
